A Bethpage man fatally stabbed his wife and injured his teenage daughter inside their home early Friday, then led police on a 25-mile high-speed chase that ended in a fiery crash at a Brooklyn gas station, authorities said.

The man, identified by law enforcement sources as Robert Crumb, 44, was subdued and arrested after charging at Nassau officers, police said.

Crumb was taken to Brookdale University Hospital and Medical Center in Brooklyn with stab wounds to his neck and wrist, according to police.

Authorities believe Crumb tried to kill himself, according to one of the sources. A motive for the stabbing hasn’t been disclosed.

Crumb remained hospitalized Friday night after undergoing surgery, according to the hospital. Charges are pending.

Police went to the suburban house on Seitz Drive at 12:39 a.m. after the couple’s 12-year-old son called 911. When officers arrived, they found the body of Crumb’s wife, Maria, 41, in a bedroom, police said.

Their 16-year-old daughter — who police said tried to stop the attack on her mother — was treated for stab wounds on the hands, forearms and ankle, according to police. Her condition wasn’t known late Friday. The son was not injured.

Neighbors on the quiet street with well-maintained lawns were stunned to learn of the violence that erupted inside the single-story house that they said served as a gathering place for the neighborhood kids.

One neighbor, who didn’t want to give her name, described the Crumbs as a “normal” and “happy” family.

“They’re always outside with their kids,” said the neighbor, who knew the family for about nine years. “They play with the kids almost every single day.”

At about midnight, before police were summoned, the neighbor said she was in her bedroom and could heard noises coming from the Crumbs’ home.

“I just wish we had heard a scream or something,” she said. “We would’ve gone out to help.”

Police were called to the Crumbs’ home in March after an argument between the father and son escalated, said Det. Lt. Richard LeBrun, a department spokesman. Further details about that incident weren’t available.

No orders of protection have been issued for Maria Crumb or other members of the family, a source said.

Relatives of the Crumbs declined to comment Friday.

The high-speed chase across three counties began about 10 minutes after police said Robert Crumb fled his house in a Hyundai Sonata.

Officers on patrol found Crumb parked on the Southern State Parkway, near the Newbridge Road exit, LeBrun said.

Crumb sped off when officers approached him and led the police on a chase on the Southern State Parkway, heading west, through Nassau County. The pursuit continued onto the Belt Parkway, across Queens and into Brooklyn.

He left the highway at the Pennsylvania Avenue exit, driving north until he crashed into a car parked at a gas station on Flatlands Avenue, police said.

The driver of the parked car, who police said was pumping gas, was not injured.

Crumb got out of his car and charged at the officers attempting to arrest him.

“Four Nassau County police officers subdued the subject amongst flames surrounding both vehicles and the gas pump,” LeBrun said.

Firefighters doused the fires and no other injuries were reported.
